Write a Java program that reads numbers from an input text file. Each line of the text may contain any number of numbers. For each line, calculate the sum of those numbers and write the sum into an output text file. Each sum must be on a separate line in the output. The names of the input file and output file are from the first and second command line arguments respectively.

For example, if the input file is as follows:

1 2 3 2 2 4

The output file should like below:

6 2 6
